3 Description

The DRV3205-Q1 bridge driver is dedicated to

automotive three-phase brushless DC motor control

applications. The device provides six dedicated

drivers for standard-level N-channel MOSFET

transistors. A boost converter with an integrated FET

provides the overdrive voltage, allowing full control on

the power stages even for low battery voltage down

to 4.75 V. The strong driver strength is suitable for

high-current applications and programmable to limit

peak output current.

The device incorporates robust FET protection and

system monitoring functions like a Q&A watchdog

and voltage monitors for I/O supplies and ADC

reference voltages. Integrated internal diagnostic

functions can be accessed and programmed through

an SPI interface.
